True/False. One mechanism that phage use to evade a cell’s restriction/modification system is to produce factors that inhibit restriction endonucleses. 

True/False. One mechanism that phage use to evade a cell’s restriction/modification system is to produce proteins that block access of the restriction enzymes to the phage DNA. 

Which component is NOT included in the PES format of a nursing diagnosis?

A charge nurse is reviewing legal guidelines for documentation with a newly licensed nurse. Which of the following should the charge nurse include in the teaching? Select all that apply.

Why was the use of thermophilic DNA polymerase enzymes so important in the development of PCR as an everyday and economical lab technique?    

You are a researcher working with recombinant DNA technology (e.g. moving DNA from one donor organism into an unrelated recipient organism) and you have two possible recipient strains to choose from. One strain has a mutation that knocks out the cell’s restriction systems and the other strain has a mutation that knocks out the cell’s modification systems.  (Neither of these damage the recipient cell’s ability to function). Which strain would you choose to introduce your recombinant DNA into and why, to increase the success of these DNA transfer experiments?

Extreme thermophilic DNA polymerases like Vent and DeepVent have decreased accuracy (fidelity) when compared to Taq polymerase because of their proofreading activity. 

Extreme thermophilic DNA polymerases like Vent and DeepVent have increased accuracy (fidelity) when compared to Taq polymerase because of their lack of a proofreading activity. 

Using the CRISPR-Cas system to genetically engineer organisms relies on our ability to make
